WINDMILL=REGULATOR.

EsPECIFICATION forming part of Letters Patent No. 387,363, dated August 7, 1888.

Application filed December 2, 1887.

T0 aZZ whom it may concern.-

Be it known that I, JOHN R. MILLER, a citizen'ot' the United States, residing at Sterling, in the county of Whiteside and State of Illinois, have invented certain new and useful Ixn-' provements in \Vindmill-Regulators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of windmill-regulators which are dependent for their action upon the height of the water in the tank into which the pump delivers.

Figure 1 is a partial section and side elevation of my apparatus; Fig. 2, a plan. Figs. 3 and 4 are detail views.

A is the usual tower or frame, upon the top of which is mounted the windmill, the latter not appearing in the drawings.

B is the pump,and Bis the pump-shaftleading up to the mill.

0 is the usual chain or wireleading from the mill to the ground, the drawing of which wire downward throws the wheel out of the wind and the releasing of which allows the wheel to again turn into the wind.

0 is the bucket suspended from the end of the wire 0, and it may hang above or in the well Said bucket is to be of proper size to hold a sufficient weight of water when filled to draw the mill out of the wind.

D is a bar having one end journaled to the tower A, as at E, and having its opposite end so connected to the bucket O or the wire C as to more up and down with said wire and bucket.

C is a valve fitted to close an outlet, 0 in Serial No. 256,750. (No model.)

G is a bell-crank having its elbow near the side of the bar D and journaled so as to move in a vertical plane at right angles to said bar, one arm,(5r,of said bell-crank extending downwardly, while the other, G", extends horizontally, away from said bar D. To the end of the arm G is coupled one end of a lever, H, the other end of which extends over the tank F. Between its ends said bar H is journaled to a fixed support, H. From the end over the tank there is supended a float, H The arm G of the bell-crank is to be made heavier than the arm G, either by making it longeror thicker or by attaching to ita weight, H. In consequence of this preponderance of weightin the arm G", said arm will tend to descend and throw the lower end of the arm G into the path of the bar D. \Vhen the tank F fills, the float H rises and tilts the lever H, so as to allow the arm G to descend and the arm G to extend into the path of the bar D, as above stated.

The operation is as follows: The bucket 0 being raised and the pump being in operation, the water rises in the tank and lifts the float H and overflows into the bucket O. \Vheu the latter is filled,it descends, drawing the bar D downward, the latter pushing the arm Gr aside until the end thereof is passed, when said end again returns into the path. of said bar D. Just after said bar Dhas passed by the end of the arm G' the valve (1 is drawn by the cord 0*, and the water in the bucket is allowed to escape through the outlet 0 but the bucket cannot rise as soon as it is empty, because the end of the arm G stands in the way of the bar D. Said bar is thus locked until the float H. descends and causes the lever H to raise the arm G and draw the arm G out of the path of the arm D. The latter and the bucket G are then free to rise in re sponse to the action of the well-knowu counter-balance, which holds the mill in the wind. By thus locking the bar D and bucket C after their descent two important objects are served: First, water is prevented from freezing in the bucket; second, said bar and bucket are held down, even though the valve in said bucket may be leaky.

It is to be understood that my invention does not include apparatus in which the bucket remains filled with water until the mill is to be thrown into action. On the contrary, my apparatus isto so operate as to drain the bucket when it reaches its lower limit and leave it empty until the tank overflows again.

I claim as my invention- 1. The combination, with the windmill, of a bucket suspended from the wire or chain by which the mill may be drawn out of the wind, a passage for the delivery of overflow-water into said bucket, a valve in said bucket controlled by a cord secured to a support above at proper height to cause said cord to open said valve when the bucket has descended to connected with said bell-crank, tank F, to receive water from the pump, the float H suspended from the lever H into the tank F, and overflow-pipe F, leading to the bucket, substantially as shown, and for the purposes specifled.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN R. MILLER.
